They had two non elimination legs in season 12. And we had a new penalty (that was given in the next episode, sorry Michael couldn't resist). The speed Bump where the teams had an additional task that only they had to do. Those teams were Kynt & Vyxin in India (after last place in Italy), and Tk & Rachel in Taiwan (after last place in Japan).

We had six teams leaving through Bangkok airport to Delhi. That assume that the pit stop in Siem Reap was a non-elimination stop.

Probably an elimination stop in Delhi, so that leaves five teams on the way to Dubai.

Two more elimination stops, and probably two more non-elimination stops.

So we have four more locations before the return to USofA

Here is where the concept of non-elim in Siem Reap was first made public. I just ignored it then because I don't agree, which is probably the best approach now unless we obtain specific supporting information.

I cannot give you a link sorry because cannot find it but that is what I saw, no I didnt hallucinate and yes it is probably just speculation so please dont get your hopes up

I found a link on the Amazing Race Fan Wiki here but it looks more like just one person's random speculation rather than a fact, especially when you read their country predictions based on what we know now
